Solution
Solution Steps
Step 1: Calculate Gross Monthly Income
To find the gross monthly income, divide the gross annual income (\$45600) by 12.
\[ \text{Gross Monthly Income} = \frac{45600}{12} = \$3800 \]
Step 2: Maximum Monthly Mortgage Payment
Calculate the maximum monthly mortgage payment by multiplying the gross monthly income by 28%.
\[ \text{Maximum Mortgage Payment} = \text{Gross Monthly Income} \times 0.28 = \$1064 \]
Step 3: Maximum Monthly Total Credit Obligations
Calculate the maximum monthly total credit obligations by multiplying the gross monthly income by 36%.
\[ \text{Maximum Total Credit Obligations} = \text{Gross Monthly Income} \times 0.36 = \$1368 \]
Step 4: Maximum Monthly Payment for Other Debts
First, calculate the actual monthly mortgage payment by applying 60% to the maximum mortgage payment.
\[ \text{Actual Mortgage Payment} = \text{Maximum Mortgage Payment} \times 0.6 = \$638.4 \]
Then, subtract this value from the maximum total credit obligations to find the maximum amount for other debts.
\[ \text{Maximum for Other Debts} = \text{Maximum Total Credit Obligations} - \text{Actual Mortgage Payment} = \$729.6 \]
Final Answer:
The maximum monthly mortgage payment should be \$1064,
the maximum monthly total credit obligations should be \$1368,
and the maximum monthly payment for other debts should be \$729.6.
